How Does it work?

In contrast to TMC (event-based road traffic information), TPEGTM refers to a whole set or toolkit of specifications, for offering a wider range of services to a wider range of users and devices.
TPEGTM services are defined in a modular way and can therefore vary in a number of ‘directions’:

Application – e.g. Road Traffic Messages, Public Transport Information or Parking Information. Each Application is uniquely identified by an Application ID (AID) that are allocated by the TPEG Application Working Group (TAWG) of TISA.

Transmission method – e.g. DAB digital radio, DMB, internet

Location referencing method – e.g. table-based (using for example TMC location tables) or on-the-fly (using a method that gives a location reference that works with or without maps and does not require a look-up table to decode in the receiver)

Conditional Access – whether data is sent for free or only to users/devices who have somehow established the right to receive it, e.g. by paying a subscription. Encryption of TPEG data is possible by means ofStandardised Encryption Indicators which are allocated by the TPEGApplication Working Group (TAWG) of TISA.

The term “profile” is used to define a combination of the above which, together, make up what you might think of as a single TPEGTM service. For example:

displaying traffic incidents on a map graphic and supporting re-routing or route optimisation

displaying public transport status information on a cell phone screen

TPEGTM Services today

TPEG is available in many countries around the globe. Any TPEG-service is uniquely identified worldwide by a TPEG Service ID (TPEG SID).
